Quick Start

Prerequisites:

• Enable Firebase Authentication with Email/Password provider
• Create a user account with the same email as ownerEmail

const express = require('express');
const fireengine = require('fireenginecms');
const app = express();

app.use('/admin', fireengine({
  adminCredentials: './firebase-admin-key.json',
  webappConfig: './firebase-config.json',
  ownerEmail: 'admin@yourdomain.com'
}));

app.listen(3000);

Configuration

FireEngine can be configured either through code (in your application) or environment variables - choose what suits your development workflow. When using environment variables exclusively, the config object becomes optional. All FireEngine runtime environment variables use the FIREENGINE_ prefix:

FIREENGINE_FIREBASE_PROJECT_ID=your-project-id  
FIREENGINE_FIREBASE_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----..."
FIREENGINE_FIREBASE_CLIENT_EMAIL=firebase-adminsdk-abc123@project.iam.gserviceaccount.com
FIREENGINE_OWNER_EMAIL=admin@yourdomain.com

Schema Customization

FireEngine automatically detects your Firestore collections and generates admin interfaces. You can customize these schemas:

app.use('/', fireengine({
  // ... other config
  schemaOverrides: {
    "users": {
      title: "User Management",
      titleTemplate: "${displayName} (${email})",
      fields: [
        { name: "email", type: "string", required: true },
        { name: "displayName", type: "string", required: true },
        { name: "role", type: "string", options: ["admin", "user", "moderator"] }
      ]
    }
  }
}));

Deployment

FireEngine can be deployed anywhere Node.js runs:

Express Server:

const express = require('express');
const fireengine = require('fireenginecms');

const app = express();
app.use('/', fireengine(config));
app.listen(3000);

Using Environment Variables Only:

const express = require('express');
const fireengine = require('fireenginecms');

const app = express();
app.use('/', fireengine()); // Config object is optional when using env vars
app.listen(3000);

Firebase Functions:

const functions = require('firebase-functions');
const fireengine = require('fireenginecms');

exports.admin = functions.https.onRequest(
  fireengine(config)
);

Configure and deploy.
